Superfast camera captures cone-shaped wakes of light

Pulses of light can leave behind cone-shaped wakes of light, somewhat similar tocone-shaped sonic booms created byaircraft flying at supersonic speeds. Now, a superfast camera has captured the first-ever video of these events. To capture video of these elusive light-scattering events, the researchers developed a “streak camera” that could capture images at speeds of 100
